Be it known that l, ALBERT HEIMANN, a

citizen ofthe UnitedStates, residing at Newv York, in the county of New ork and State of New York, have invented neuT and useful Improvements inA Weighingand Advertising rl\flachines,` of which the following is a speciiication.r

This invention relates to automatic weigh-l ing machines and a principal object of the invention is to produce amachine,` the niecliaiiisinof which is constructed so as to prevent the machine from being operated repeatedly unless a certain part has been previously moved, such for example as a coin -Aifurther object of the inventionis duce a combined weighing and advertising machine, constructed and'arranged so that` a movablel advertisinjgy device is actuated peever the weighing mechanism is-actuated;

A further object of the invention is to provide automatic means for effecting the 1 energizing or. rewinding of the motor.

A further object of the invention is to providev very simple means for effecting adj ustment of the weighing'mechanism AA' further objectofthe invention is, to provide an arrangement whereby when the ad vertismg device` is actuated through aliand'y operated member the opeiation ofthe hand operated member winds the motor, and furtherniore to construct thepazrts so as to prevent injury to the motor o r tovr anyjof the mechanism from repeated 4actuation of the handoperated member.

A .further object of the invention is to construct the .machine in suchV away as to prevent it from being fraudulently operated.y

Referring more particularly tothe parts andespeciallyto,Figures l` and 3,71 represents the case'ofthe machine which is prefeiably mounted upon a post at the foot of l which a weighing platform i'sjmo'unted, for example in the manner indicated'. in Figure. 1 in my co-pending application, Serial No.-

. 143,610. yTheease isi preferably provided on its sideswith bow windows 2 and at an elevated point with a front window 3. Behind the .windows Vare provided `two :rotatable drums l the central shafts of which are rotated through bevel gears 5 `or iiiany other suitable manner from a horizontal counterl section talenabout Aon the shaft 6.4 A similar drum 7 is mounted be.

hind the window 3 and this'drum is-driven by gear wheels 8 and 9 from the counter shaft 6.' These drums l, 4l` and 7 constitute parts Vof amovableadvertising device and their surfaces are divided 'circumferentially intorzones; eachhzone has a different advertisingr device. j j v l g Iprovide means for periodically actuating these advertising devices'through a motor f, and also independently of the-motor through parts .which controlthe actua-.tion4 of theV weighingmechanism, I shall first describe the preferred form ofthe weighing mecha,- .nism and the indicatingmechanism together with the meanswhereby the operationof the indicating mechanism maybe readily controlled through the movement of a coincontrolled part.. Fromthis arrangement a pere son standing upon theweighing platform can operate rthe knobV or handle which ordinarily would release the indicating mechanis'm .without producingiany effect unless he has previously insertedthe proper coin inV the machine, except however7 that the operation of this knob or handle or other hand operated memberVwhe-ther a coin has been inserted or not, will operate to effect the winding of the motor and may effect they immediate actuation of the advertising device. ln order to accomplish this I prefer to provide a sulaporting bracket 10 attached to the rear wall of the case (see Figure 3) and this supporting bracket supports a fixed crosshead 11, to the oppositely disposed arms of which are attached weighing springs 12, and the lower ends of thesefsprings 12 support a movable or floating crosshead 13 which is carried by the upper end of a weighing rod or bar 14, the lower end ot which is connected in any suitable manner with the levers under the weighing platform, which levers and platform it is unnecessary to illustrate, as they may operate in any usual manner. lhen the person stands upon the platform the springs 12 will bey extended and the crosshead 13 will move downwardly a distance proportionate to the weight of the person. This crosshead 13 therefore, constitutes moving part of the weighing mechanism and. I employ it to determine the amountV of movement of the indicating needle or pointer of the indicating mechanism.

I shall now describe the indicating mechanism and the manner in which it is controlled by the member 13. Referring particularly to Figures 1, 3 and 4::

The indicating mechanism preferably comprises an indicator dial 15 before which there is mounted an 'indicating needle or pointer 16 which is carried on the end of an indicating spindle 17. This spindle is preferably mounted between anti-friction rollers 1S (see Figure 3) and carries a pinion 19 which meshes with the teeth 2O of aI rack 21, the teeth being formed on the edge of a slot 22 in the rack. lThe upper end of rack 21 carries damper means which may be in the form` of a piston 2?; which is received in an air cushioning cylinder 24, and the upper end of the cylinder may be provided with adjustable needle valve 25 for regulating the admission of air. The lower end of this rack 21 rests upon` but is unattached to a floating stem 26. the lower end of which stem rests in but is` unattached to a socket 27, which is formed in the upper side ot crosshead 13. lhen a weight is placed on the weighing platform the crosshead 13 moves downwardly and comes torrest at a lower Vposition and this permits the rack 21 to descend; and through the medium of the pinion 19 this rotates the pointer 16.

`I provide means for normally checking the operation of the indicator pointer and this is preferably accomplished by means of a check device 28 comprising a ratchet wheel 29 secured on the indicating spindle 17, and

having inclined teeth co-operating with a detent pawl 30. This pawl P30 is normally in the position shown in Figure 4l, but it may be moved into the position shown in Figure 5 to release the ratchet wheel 29 and permit the pointer and the ratchet wheel 29 to rotate in the direction indicated by the arrow in Figure 5. )Vhen the pawl is in the position shown in Figure 5 the ratchet wheel 29 can rotate but the mechanism which releases the ratchet wheel from the pawl preferably operates in such a way that the ratchet wheel is temporarily held against rotation until the opeiatingi` handle of the machine returns to its normal position. This is to prevent persons from holdingr the operating handle or knob fixed at any point and then attempting to weigh more than one person.

I shallV now describe the mechanism for controlling the pawl 30 and temporarily detaining the ratchet wheel 29 when the pawl El() is released, until the handle returns to its normal position, This mechanism controlled by a movable part, the position of which depends upon whether a coin has been inserted in' the machine. The h and operated member referred to above is preferably in the form of a `knob 31 which may be moved up and down in a slot 32 in the cover plate or front plate of the machine, sai d lfnob being formed on a slide 34 on the inner side of the plate which normally pulled upwardly by a spring 35. This slide 34 has a socket which engages a dog 36 on a lever 36 (see Figure 1). Then the lever 536 is pulled down it operates through a linhY 37 (Figure 1) to pull down a slide 38 which is mounted to slide if'crtically in suitable guides 39. 0n the upper portion of the slide 38 there is attached a movable part of actuator 45]. which is preferably pivotally niounted at -l-2 on. the slide so that a` small screw /'l and a slot #lili in the actuator permit a limited pivotal movement of the actuator on the slide. )Wien the slide is in its normal or elevated position the upper end of the actuator 41 engages a roller 415 on a temporary detent pawl 46 and holds the same up as indicated in dotted lines in Figure 1, against the action 'of a spring 4:7 which tends to swing the pawl 16downwardly. lt the hand operated member or knob 31 is moved down and back again without the insertion of the proper coin the temporary dctent pawl -llfl will be thrown into active operation but there will be no release of thc normal detent pawl on the return movement of the knob. and hence no weighing. will occur. Any suitable connection. may be made from the pawl 4G to the ratchet wheel. ,in the present embodin'ient of theinvention when the temporary detent pawl t6 is released a V shaped notch 1S in its end engages with a pin 4.9"l on the ratchet wheel 29 and holds the ratchet against movement; and it will continue to l Ui hold it until the actua-tor 41 returns to its normal position.` l control the detents 30 and 4G through the operation of the actuator 41 and prefer to control the actuator 41 by a trip device 49 which I shall now describe, referring' particularly to Figures 1 and 4. This trip device consists ot two lever arms 50 and 51 which are pivotally mounted upon a common pin 52 iiXed `oii the trame of the machine. The arm has a projection 53 enga-gingr the edge of the ai'ni 51 to limit a separating angular moveinentfo't the arms 50 and 51, and the arms are normally held in this relation by a coil spring 54 disposed around the pin. rIhearm 51 has a toe 55 against which thrusts a stem 56 which is guided to slide vvertically in the machine, this stem being moved in any suitable ,ii'ianneig as tor instance hy an instrumentality formingv part ota different apparatus, an example ot which is disclosed in the companionapplication ret-erred to. It a coin has been inserted in such other apparatus ot which stem 5G formsa part and before the slide 38 moves downwardly the stem 56 will move upwardly and will roch `the toe toward the lett (coiinterclockwise to the `position shown in Fig. 4) and this will bring a dog 57 on the `upper end ot arm" 51 directly into the path of movement ot the horizontal arm 58 ot the actuator 41, setting the parts ready tor the downward movement ot the slide. )sow when thcslide 38 descends, the arm 58'by engaging` the .isi'ittached to the upper end of the link 37 andthe other Yend ot which is yattached to the vertical arm of the actuator. This spring is arranged so that when it is inthe position indicatedin Figure 4 the direction of pull of the spring is on the-letto't the center ot the pivot 42 and so that in the other posi- 1 tion ot the actuator the spring pulls 'on the other side ot the pivot point; in'other words,

thespring tends Lto hold theactiiator in. either of its two positions.y bfiipposing that coin has been' inserted and the knob 31' hasfbeen moved down as tar as it will-go; the parts will then occupy the position indicatedin Figure 4, that is, the upper end rot the actuator' 41 will come directly iinderthe sliding' stem G0 into position to torce the steniupwardly upon -the return movement of the slide which takes place when' linolo 81 is released. In ordery to torni aV damper :for nits. movement the upper end ot this stemV carries av piston 61 sliding in a suitable air cushioning cylinder G2. The upward move-Y -uieut ot thel stem G0 operates to release ther pawlV 30 and for this purpose prefer to provide the stem with a 'laterally projecting 'pin 63. lVlien the stem 60' slides up the pin 'pawl Figure 5 shows these parts when the slide 38 has nearly reached the limit ot its upward movement, and as the limit of this upward movement is approached the arm 58 strikes a fixed stud 70 operating as a trip,

,the continued movement then causing this stud to throw the actuator toward the ri Veht (see Figure -1). Y As the actuator moves towards the right it engages the roller 45 to raise and hold up the temporary detent pawl 46. Furthermore, as the slide 38 reaches the f limit of its upward movement a roller 71 on the link 37 engages the arm 5() and rocks it toward the right (see Figures 1 and The rocking movement of the lever 50 is imparted through spring 54 to the arm 51 so that the arm 51 isthen moved to its normal oriiioperative position wherein the dog 57 is out ot the path ot' the arm 58 ot the actuator 41. A.` small stop-pin 72 co-operates with shoulders 73 onthe arm 51 to limit the movement of the arm 51 in either direction and furthermore the two arms50-51 are constructed so as to hold themselves in either position .in which they are left.

I prefer to provide a motor for driving vthe drums: 4, 4 and 7 ot the advertising device, -and this motor operates in such a Yway that it periodically causes the forward rotation ot the advertising' drums. This is pret'- erably'efected through the medium ot an. escapeinent wheeland a spring, the .mode

of operation being that tlieinotor places thc spring under stress and then the escapement wheel is permitted to "make a. 'forward rotation, which is transmitted to the advertising drums. ln order to accomplish these results the motor 74 is provided w'tli au hour shaft 75, thatwis a shattwhich rotates at some predeterminedspeed. As this shaft 75 rotates, it places in stress a coil spr 76, one end ot weich is driven by the sh tt 7 5 and the other end of which' is connected with an escapement wheel 77. The end ofthe spi-ing 7G which is connected with `the .shaft 75 is preferably attached to a cam'wheel 79 which is lrig-id on the shatt- 7 The othei` end of the spring is attached vto an arm 7 8a (see Figure 7) that is clamped Jfriction tight between the wheels 77 and 87. 'When' the shaft rotates, at the same time that lit is put-` ting the spring- 7G i n stress itis also rotating` cam wheel 79 through the medium-oft a pawl 8O which is pivotallyattached to the cam wheel and which entrages the teeth ot the ratchet wheel 78. This Vcam wheel 7 9 hasa wavy edge with alternatingprojections 81 and hollows or recessesI 82. This wavy edge engages pins 83 'on a rocker 84 which is rigid on a rock shaft 85 which carries :a

vhand actuated verge 8G. About the time that the spring 7G has been placed under stress the cam comes into such a position that it vWill move the rocker S41', for example as in Figure 7 the rocker 84 Will be rocked toward the lett so as to rock the verge 8G on its rock shaft 85 and cause the verge to release the escapement Wheel; and the escapement wheel Will. then rotate through one tooth' space. This movement ot the escapeinei'it wheel causes a ttor` ward rotation ot a gear .vheel 87 Which is looser on the end of the shaft but which is rotated with the escapement Wheeh the gear Wheel ST meshes With a gear Wheel 8S on the atoresai d shatt G which imparts rotation to the advertising drums.

l provide means iter eltecting` the Windine i p ot the motor T41- automatically by the actuation et the hand aetuated member 31. For this purpose the motor 1 /1, which may he an ordinary spring` motor is provided with a winding shaftv 99 carrying a large ratchet wheel 90 with which co-operates a spring pressed pawl 91 'tor nniintaining the spring in its Wound up comlition. ln order to rotate the. ratchet wheel 90 to Wind up the spring', the sha'tt S9 is provided with a pawl carrier carrying a pawvl 93 which engages the ratchet wheel, and this pawl carrier is rocked to and tro through the operation ot the lever 3G. 1n order to impart this move-meut troni the ever 30, preter to provide a rocker 9-1- Vwhich operates the pri/wl carrier 92 through a link 95 and a loose arm 9G which is connected to the lever 94 by a spring' 97. A link 9S may ,in'ipart an upward movement to the lcv-rer 941 and this eX- erts tension in the spring 9T which operates the rocker 92. In order to operate the link 98 its lower end is eoi'niected with a lever 99 which is pivoted at 100 and. formed an arm o1 a segment 101 which n'ieshes with a segment '102 rigidly attached to a shaft 103 which carries the lever 30; a spring 101 restores this lever 36 to its normal elevated position.

The cani 7 9 may normally be actuated at any time through the operation o1 the hand operated knob 3,1` To accomplish this I provide the rock-lever 941 ivith a link A, the upper end of which is pivctally attacl'ied to a pawi carrier 100 which carries `a pawl 10i', and this pawl is pressed by a springY 108 so that it may engage the teeth o1 a ratchet wheel '109. This hand actuated ratchet Wheel 109 has a tlexible or lost motion connection with the cam T9 so that the ratchet Wheel may actuate the cam. For this purpose provide a. pin 110 on the ratchet Wheel which may engage the edge ot a. spoke 111 ot 4the cam (see Figures 7 and 9). The ratchet Wheel 109 is periodically rotated by the escapement Wheel 7T so `as to keep the pin 110 close up behind the spoke 111, that is, in the position shown in Figure 7. This is effected tlirougrh the medium oli a longl pin 112 which is rigid with the esci pement Wheel and which eX- tends iinvardly towards the motor 71 parallel with the shaitt 77, and with its inner ci l received treely and movaliily in a short circunrteren al slot or notch 11i-i in the hand actuated ratchet wheel 109. Now it the ratchet Whe/l V109 is actuated by hand 'with the parts in the position shown in lief ure T, the paw] 10?' will move back and. catch a tooth and on its return movement will en- ;ljane that tooth and rotate the ratchet Wheel 19 so that the pin 11() will rotate the cam, his will leave the ratchet nf'heel. 109 in a inwardly rotated position with respect to he long' pir 112, that is. the shoulder 1111- it Vthe righ hai d end ot the slot 113 will ie suhstant ally against the pin 112. Now it it is immediately atteniplcd to actuatc the ratchet wheel 109 again through the medium ot' the link 105, the pawl 10il will slide back until it strikes the next tooth -on the ratchet Wheel 109 but it will not be. able to pass over and etfectively engage this toot-h because there will be nothing to prevent the ratchet Wheel 109 it'rom rotating towardthe right; in other wort s, the pawl 107 can ac tuate the ratchet Wheel when the long pin 112 is near the Ltorward end oi theslot 113 and against the shoulder 115 `formed by the forward end of the slot, becausel this shoulder will otter a resistance to the backward rotation oit the ratchet wheel and permit the pawl 10T to pase` over and effectively engage the next tooth o1" the ratchet Wheel. (7)1: course7 when the ratchet. wheel 109 is actua-ted by hand in this way, the pin 110 Will advance the cam 79 and effect the release ot the escapememiv wheel which will cause a movement of the advertising drums; hence, ,it the parts are in the position shown in Figure 7, it is evident that the hand operated member 31 can operate the advertising` device once, but no injury can be done to the adverising; device by repeated actuation ot the knob 31. i

Vhen the motor is simply dri ving the cani the escapement Wheel 77 periodically advances and at each advance7 the long pin 112 comes up against the shoulder 115 and r0 tates the ratchet Wheel 109; and this keeps the pin 1107up against the spoke. In other Words7 the escape-ment wheel causes the ratchet Wheel 109 to follow up the cam.

lNhenever the Weighing mechanism is actuated and the paivl 30 has been raised, the stem 60 Will gradually gravitate back to its normalloivest possible position, (see Fig ure 1) as the air leaks past the piston `61. About the time that the crosshead 13 comes to rest, that is7 when the pointer 16 comes to rest, the paivl 30 Will come back into engagement with the teeth of the ratchet Wheel 29 and Will thereafter permit the Y i t i pointer .to return to zero but will not permit the machine to Weigh another person until the pawl is again released through the medium of a proper coin.

As will be understood, return of ratchet Wheel 29 to its normal position is rnot prevented by pawl this pawl beingr held out of the path of movement of pin 49 by actu ator 41 until knob31 is again moved downwardly, whereupon pawl 5-16 again engages pin 49a.

I prefer to construct the machine so that the motor 74 may -be wound up by hand independentlyof the hand operated knob 31. In this connection reference is had particularly to Figure 1. Inthe upper part of the machine there is mounted a tubular stub shaft 1167 the end of which is formed into an angular head 117 to which a wrench may be applied. By rotating this head 117 motion is transmitted througlra sprocket chain 118" to a sprocket Awheel 11.9 on thewinding shaft 89` of the motor.

I prefer also to construct the parts so that `the weighing` scales'can be adjusted readily from the outside of the machine. In order toV accomplish this I .prefer-to mount the fixed crosshead 11 on pivots 119 (see Figure 3) which are formed on the upper end of al 30."

tubular adjusting stud 120 Awhich, is guided vertically in the` aforesaid bracket y 10;.V

an ordinary wrench maybe applied.

Through this stud or sleeve the aforesaid stem 26 passes upwardly. The upper porvtion of this sleeve 1201s threaded so as to receive an adjusting nut 121, the lower sidev of which is seated on the upper side of thel bracket 10. A spring 122 around the lower end of the sleeve thrusts against the `under sider of the bracket and alsothrusts against `a collar 1123 attached tothe lower end of nut 121 I provide it with lear teeth so that it virtually `forms a gear wheel` and meshing with it, there is ai pinion 126 disposed'r at the lower end; of af spindle 127, the upper end of` which carries' a small worm wheel 123. This'worm wheelv 128 may be rotated by means of a wormi 129* attached on the inner end of a shaft`13() which has a reduced extremity Vterminating ina 'flattenedf head*` 131 Aadjacent to the head 11.7, and to which' I prefer to'construct `the cover plate 33 so that it `liesV behind the plane in which the pointer A16 rotates and I prefer to provide an opening 134 which will nass over the pointer when the pointer is inan unvlfieeeeo extended` position, l and I n provide means for extending they pointer after .the` cover platek has been placed in position. ^For thispurf pose'Iprefer towmountthepointerl so as to Vslide longitudinally in a holder or pointer head 135 which is securedonthefend of the spindle17.A On the head a spring plate 136 or similar means may be providedfor frictional'ly engaging the pointer to hold the same in place, at the same time permittingl hook 140 beyond the rockshaft 1414 which supports the arm 138. This rock shaft 141 has ashort arm 142 to which a link 1h43 is attached andthe lower end ofthe link 143,

is attached toa lever 144, one end of which liesV near a lock ,145 attached 'on the inner side of the cover plate, and having-a locking locking bolt will lock the cover plate againstY y i removal. For this purpose I prefer to provide a hook or latch arm 147 Vwhich is piv-4 hooked end engages a catch 150 attached to.

the rca-r side Vofthe cover plate, and this prevents the cover plate from being pulled outwardly until the lock bolt iswithdrawn by means of the key. Ofcourse, other fastening means are provided at other points of the cover, if desired. 1

I .shall nowQbri'eiiy` explain mode of operation of the machine.

A person desiring to be weighed standsv iinonthe weighing platform and-this pulls down the; 'Heating crosshead 13v andextends the springs 12; Athis of course, causes a `depression of thc'floating crosshead 13 to a'. point depending' upon the amount of thewe'ight. IInlessfa coin has been. 'inserted no :Weight will be indicated at the dial for the reason that although the stem 26 lmay move" downL vardly the check paWl 30 will prevent the ratchet wheel-` v29 from rotating and consethe general quently the pointer at the dial will not ros. Y

tate.. If, however, the person standing on the platform has inserted the proper coin and then moves down the operating knob 3l, the arm 36 in movingr downwardly will cause an upward movement ot stem 56. The upward movement of stem 56 (see Figures l and 4) will rock the arm 5l over toward the left. In addition to this7 throiiejh the medium of the link 3T the lever 36 will pull down the slide 3S and with it the movable actuator 4l: and near the latter parlr of its downward movement the arm 58 of the actuator will enga-ge the dog 57 on the arm 5l and this will trip and rock the actuator 4l toward the lett and into the position in which it is shown in Figure t. This will bring the upper end ot the vertical arm o't' the actuator directly under the lower end of the stem (30. Now when the knob 8]. is released it moves upwardly again under the action o'l the springs 35 and 104; hence, the slide 23S will move upwardly, and as it moves upwardly the sgi-ingrT 59 holds the actuator al in its active position as in Figure 4; hence, in its upward movement the actuator il will move the stem 60 upwardly; as the stem GO moves upwardly, its lateral pin (3C-l actuates the lever (Sit, and through pin (S5 actuatesl the levers G6 and 68 which lift thc check pawl 30 off the ratchet wh el 29; after check pawl 30 has been raisech ratchet wheel 29 is held only by cngagement ot pawl 46 and pin 49, and this engagement is broken by the shift in position ot actuator 4l by trip 70 as the slide 1 reaches the upper extreme of its movement.

Release of the ratchet wheel 29 of course, permits the rack 91 to descend by gravity until the rack rests upon the upper end ot the stem 26. the position of which is determined by the amount oit the wei ght on the weighing platform; the speed ot descent ot the rack is controlled by means olf the air cylinder 24; and air valve 25. The air cylinder G2 operates as a damper or check to prevent the immediate return of the stem 60 iti-oni the elevated position in which it is lett by the upward movement ot' the actuator 4l and this prevents the pawl 30 'trom descending' immediately into engagement with the ratchet wheel 2), However. at about the time that the pointer 1G will have ceased to vibrate, the pawl 30 will return into engagement with the ratchet wheel 29 and prevent any further movement oie'l the indicating pointer. The printed directions to the person using the machine `will be to the elfcct that the knob should be moved down and then released. ln' case it is attempted, however, to commita fraud by holding the knob in its return movement at a pointl where the `pawl 30 would be held ott ot Aits ratchet wheel, I provide the temporary holding means or pawl 4G; this pawl is normally held up in an inactive position (see Figure l) -but when the actuator al moves down the pawl engages the pin 49" (see Figures 4t and 5) and operates as a temporary detent device to prevent the actuation ol the indicating' mechanism 4ot the instrument until the actuator has returned to its normal. position ot rest. In the upward movement of the actuator and at about the end ot its upward movement, the horizontal arm 58 thereolt strikes the lixed pin T0 which moves the actuator over so that the upper end ot its vertical arm strikes the roller and thereby moves the detent pawl l-(i up and holds it in its inactive position,

Each depression and release ot the knob 31 gives a downward and upward. movement to the link 9S which through the lever 94 and spring 97 actuates the rocker 92, and this winds up the spring motor 74- by rotat-ingthe winding shaft S9.

The details ot the mode ot operation ot' the mechanism for controlling the rotation of the advertising drums have been already described but will be now again briefiy set forth.

The rotation ot these drums is controlled by the escapenient wheelp (io-operating with a verge 86. lVhenever the lever 941C is actuated, the pawl 10T is operated and this may produce the rotation ot a hand o erated ratchet wheel. This may actuate the cam 79 which controls the verge SG and causes a release ot the e vapenicnt wheel; the cscapement wheel is rotated in this way by means of a spring 76 which is constantly beiner placed under stress by the rotation ot the hour shaftt T5 o't the motor. ln addition to actuatingI the advertising drums through the medium ot the knob 3 1 they are also actuated periodically by the motor mechanism which operates to continuously rotate the cani 79; and the cani driven in this wav by the clock periodically actuates thc verge SG to release the cscal'iement wheel TT and cause the rotation ot the drums.

By reason of the 'Fact that one end o'i spring 76 is attached to a Yfriction tight arm '78% it is evident that by movincy the arm slightly forward or back (with respect to the direction oit' rotation) the stress in the springr may be adjusted or regulated.
